Modular quick-replacement power battery unit of electromobile

Abstract

The invention discloses a modular quick-replacement power battery unit of an electromobile. The main body is provided with a plurality of same battery cells, the middle parts of the two opposite sides of each battery cell outwards extend and protrude to form a positive tab and a negative tab, the two ends of each battery cell are fixed on two vertical support plates by the positive tab and the negative tab, the battery cells are connected in series to form a battery module with the support plates, the battery module is arranged in a rectangular battery box, a gap between the battery box and the battery module is filled with a heat conduction material, and a positive electrode and a negative electrode of the battery module are jointly led out from a surface of the battery box and are arranged to be a positive connection plug and a negative connection plug. The power battery unit adopts a modular design, can be configured on different vehicles and is high in universality; during configuration, different configuration modes can be achieved according to actual conditions of a consumer; and through a battery replacement mode, the problems of long charging time and high charging requirement are solved.

Description

technical field [0001] The invention relates to the technical improvement of electric vehicle batteries, in particular to a modular quick-change power battery unit for electric vehicles, which belongs to the technical field of electric vehicles. Background technique [0002] As the world's energy situation continues to be severe, new energy vehicles that do not use traditional fuels are increasingly being advocated and encouraged by everyone. Among them, electric vehicles have become the key direction of enterprise research and development, and with the development of technology, they have also realized commercial applications and gradually entered people's lives. Although electric vehicles have already been driven on the road, they still face many problems, which is also an important reason for their slow development, and the main restrictive factor is the power battery. At present, the power battery mainly has the following defects: 1. The cost remains high, accounting fo...
